description="
A library of integers.

ISL is a library for manipulating sets and relations of integer points
bounded by linear constraints.  Supported operations on sets include
intersection, union, set difference, emptiness check, convex hull,
(integer) affine hull, integer projection, and computing the
lexicographic minimum using parametric integer programming.

It also includes an ILP solver based on generalized basis reduction.
